L'UPTON, OF BALTIMORE, MARYLAND, ABSIGNOB TO THE BABTGB BROTHERS COMPANY, OF ILCHESTEIR, IABVYLAND, A. CORPORATION OF MABYLAN D Applicatlon iled January 11, 1830. Serial Io. 420,191.

rlhis invention relates to improvements in skids such as are employed in factories, paper mills, warehouses, and elsewhere for holding materials and which can be picked up, with their loads, by a lifting truck, and transported from place to place.

The skid of my invention comprises a frame made from sheet metal and having rers which are formed by folding the metal along parallel lines at right ang es to the body of the sheet. rlhe two sides of each fold are spaced apart and a plank fills this space. lllhe edges of the sheet are ilanged upwardly, and a board flooring rests upon the upper side of the sheet and upon the edges of the planks in the runners. Thus, the ex posed surface of the underside of the skid is all made from one continuous piece of sheet metal which provides smooth metallic wearing surfaces on the bottoms of the runners, and also in the central part of the body which is engaged by the lifting trucks. rllhe sheet metal runners are stiffened laterally and vertically by the planks which they en-4 close, and these planks form beams for supporting the floor boards which extend transrersely of the skid.

ln the accompanying drawings,

l is a top plan View of the skid;

2 is a cross section on the line 2-2 of lig. l; and,

llig. 3 is a perspective view of the metal frame of the skid.

Referring to the drawings, t represents the frame of the skid which is formed from a rectangular sheet' of steel of suitable dimensions. The body portion l of the frame is flat and its side edges are bent upwardly, forming flanges 22 which project about an inch above the plane of the body portion. Preferably, also, the ends of the sheet are upwardly flanged, as shown at 3, and the danges Q and 3 are secured together at their meeting points. Parallel legs or runners 4 and 5 extend throughout the length of the frame. Each runner is formed by making a fold in the metal sheet parallel with its sides and at right angles to the body of the sheet, the sides of each fold being parallel and spaced apart, ylFhus, the runner l is formed by bending its sides 4 and 4b at right angles to the body and at right angles to the part 4c which forms the bottom of the runner. The runner 5 is similarly formed. Where it is desired that the top of the skid shall be twelve inches from the floor, for instance, the runners 4 and 5 will be about eleven inches deep and the sides of each runner will be spaced apart a suitable distance so that planks 6 of substantial thickness and eleven inches in width, which are laid lengthwise within the runners, will completely fill the space between their sides and extend to the u per surface of the body l of the frame. hese planks may be secured in place by bolts 7 A wooden ooring Z coversthe body of the frame. This floor comprises boards 8, say one inch thick, which are laid crosswise on the frame between the anges 2. These boards are secured to the frame by bolts 9 which extend through the boards and through'the parts 11 of the frame bod which lie between the runners l and 5 an the flanges 2, the heads of these bolts being countersunk in the boards. The floor boards may be nailed to the planks 6, but this is not necessary.

lt is to be noted that the under surface of the skid is made of one continuous piece of sheet metal and thus smooth metallic wearing surfaces are provided for the bottoms of the runners and also for the central part of the skid which is engaged by the lifting trucks. The planks which fill the runners stiden the runners laterally and also vertically and form beams under the flooring.

ln using skids of this nature, the operator runs a lifting truck under the skid body and lifts the skid from the floor and transports it to any desired place and then withdraws the lifting truck. The skid shown in the drawings is oblong and suitable for carrying loads of cardboard and metal sheets which, in load ing, would extend lengthwise of the skid. Skids for this purpose, supported only at the corners, are sometimes broken down by reason of the operator inserting the lifting truck under the skid from the side so that when the skid is lifted the weight of its ends causes the skid to be strained at its center over the truck. In the skid of the present invention, as the runners are continuous from end to end, it is impossible to place the lifting truck under the skid except by inserting it from either end.

What l claim is:

l. A skid comprising a metal sheet having therein two parallel folds extending downwardly at right angles to the body of the sheet near its edges and constituting runners, the

sides of each fold being parallel` and spaced apart, and a wooden looring secured to th upper side of said sheet.

2. A skid comprising a metal sheet having therein two arallel folds extending downwardly at rig t angles to the body of the sheet near its edges and constitutin runners, the sides of each 'fold being para el and spaced apart, and planks extending transversely of the folds on the upper side of the sheet and secured to the sheet between each fold and the adjacent edge of the sheet.

3. A skid comprising a metal sheet having two parallel folds extending downwardly at right angles to the body of the sheet near its edges and constituting runners, the sides of each fold being parallel and spaced apart, wooden planks filling said folds, and a wooden iiooring secured to the upper side of said sheet.

4. A skid comprising a metal sheet having two parallel folds extending downwardly at right angles to the body of the sheet near its edges and constituting runners, the sides of each fold being parallel and spacedapart, wooden planks lling said folds, and planks extending transversely oit the folds on the upper side of said sheet and secured to the sheet between each fold and the adjacent edge of the sheet.

5. A skid comprising a metal sheet having two parallel folds extending .downwardly at right angles to the body of the sheet near its edges and constituting runners, the sides of each fold being parallel and spaced apart and the side edges of the sheet being flanged upwardly, and planks extending transversely of the upper side of the sheet between said anges and secured to the sheet between each fold and the adjacent flange.

6. A skid comprising a metal sheet having two parallel folds extending downwardly at right angles to the body of the sheet near its edges and constituting runners,` the sides of each fold being parallel and spaced apart and the side and end edges of the sheet being Banged upwardly, and a wooden flooring covering the upper side of said sheet between v said anges.

In testimony whereof I aiiix my signature.
